“…These compounds secreted granulocytes, an active form of ProPo granules, which were converted into ProPo enzyme. The polyphenol compounds are easy to be oxidized and converted from oxidase phenol into quinone oxidase that is able to kill pathogens and can produce melanin [24].…”

Background and Aim: There has been continuous effort to search for alternative medicinal plants that are applicable to ameliorate viral disease on shrimp pond. This study aimed to examine the effect of Acanthus ilicifolius leaf extract on clinical symptoms and non-specific immune response of black tiger shrimp (Penaeus monodon). Materials and Methods: A total of 330 shrimps were equally assigned into three extract forms (crude extract, ethyl acetate extract, and n-butanol extract, respectively) in which three levels were provided for each extract. Negative control (without leaf extract) and positive control (with oxytetracycline at 0.05 mg/mL) were used, giving a total of 11 experimental treatments. Results: The results showed that shrimps induced into all form of leaf extracts had significantly higher survival rates, clinical symptoms, and pathological anatomy than those negative control (C–) and positive control (C+). Total hemocyte cells, granulocytes, percentage of phagocytic, and prophenoloxidase activity were similar among leaf extract treatments (p>0.05), but those groups were significantly higher than those of C– and C+ (p<0.05). Conclusion: n-butanol leaf extract at 300 mg/L is suggested to be the most effective treatment since it showed the highest efficacy on the parameters observed. Thus, it is possible to use the leaf extract of A. ilicifolius on-farm as a strategy to enhance bacterial disease resistance and prevent mortality.

“…Differences in decomposition rate are influenced by species diversity, leaf chemistry and soil condition. Rhizophora racemosa leaves have high phenolic content which has antimicrobial properties (Eswaraiah et al, 2020; Mitra, 2020), which slows decomposition (Friesen et al, 2018). Surface litter decomposes faster than sub‐surface litter because of aerobic condition (Figure 2a) (Chale, 1993).…”

“…The final crude extract was dissolved in 100% dimethyl sulfoxide (DMSO; Sigma-Aldrich Chemicals Pvt Ltd, Merck, Bangalore, India), made to final concentration of 100 mg/mL and used for antiproliferative studies. The concentration of DMSO maintained in the wells was less than 1%, which is not toxic to the cell lines ( 8 , 9 ).…”

Mangroves contain a wide range of bioactive compounds with pharmacological activities. In the present study, we analysed the separation and detection of phytoconstituents with the methanol extract of Ipomoea tuba leaf using gas chromatography-mass spectrometry (GC-MS) and tested its in vitro cytotoxicity effect against MCF-7 and HeLa cells. Phytochemical compounds such as docosanoic, octadecatrienoic and cis-9-octadecanoic acids, triterpenoid γ-sitosterol, and terpene alcohol in methanol extract of I. tuba leaf were identified. Furthermore, in vitro antiproliferative activity of the extract of I. tuba leaf was evaluated using MCF-7 and HeLa cells. The results indicated a reduction of cell viability of 37.43 and 41.89 % of MCF-7 and HeLa cells respectively. The methanol extract of I. tuba leaf proved to be effective in protecting the cells against oxidative stress. This is the first report on the in vitro cytotoxicity effect of I. tuba leaf extract on MCF-7 and HeLa cells.
